Man I love JITB food! I've been eating JITB for 50 years, maybe longer! The new menu options are really good. I just can't eat there too often or I know I'll gain weight! Seriously good food.

I was 1 of 2 cars in line. Ordered an extreme sausage and a biscuit sausage. Paid waited 30 minutes after paying for food effectively my whole lunch break for a munchies box just filled with regular fries. And a taco. I want my 12 bucks back.. what a dumpster fire 🔥

The manager, The Mexican lady with the bad attitude. I tried to order tacos without lettuce and she said the can’t do that? Why? And you what she does? She only put lettuce 😳. Don’t go here worst customer service. You don’t deserve to be here in diamond bar. This isn’t my first time there. She’s always in a bad mood. I mean always. I hope she reads this comment. She shouldn’t be working there in she acts like that. That’s messed up. I’m a nice guy but when you do that it leaves a bad taste in my mouth. Next time I am reporting her. I will literally call and find her hire ups. I got 16 tacos and everyone was just lettuce. 😤

I would have to say drive thru service is terrible. Husband and ordered sour dough jack, large root beer, (was entered as large coke, that was corrected at the window0) The problem is I ordered a grilled chicken sandwich. I thought something was amiss by the price of $2.99, then it was corrected to $4.99. Got home to find two breaded fried chicken on a bun. Not what I ordered. Called JACK IN THE BOX to say did not get what I ordered and I am not eating this.

Jack in the box is good. Can't disappoint. Pretty consistent as well. Wish they could bring back cheese and bacon wedges. Those were my favorite.

No one at front counter, had to drive through. I ordered #4 should be $7.59 I was charged $10.59.?. I went inside to get a $3.00 PLUS!! tax refund and the correct meal (wrong food) . No one new how to do a refund, called 2 shift managers. She finally agreed to give me a refund of (get this?) $1.40 because she said there's tax on it? That's over 50% tax pluss I already paid tax of 9.5% and that would be over 60% total tax. That I paid and should have been refunded the tax not charged more tax W.T.F.??? Pluss when I did finally get the correct food it looked like they stepped on the burger? And there was something wet on the frys!! I through the whole thing out... don't go to this location!!! They should close it. And by the way when I asked why where they charging me tax again all of a sudden none of them spoke English..

I hate sticky floors... And like everywhere was sticky. Why?!? Other than that, it's fine. Egg roll is good and tacos aren't bad. But as I have gotten older, the fried stuff doesn't always agree with my stomach 😵 That's all I got.

I hardly eat fast food anymore. I stopped eating here because a lady in the drive thru was rude all the time. First time back in about a year and service wasn't bad but I Definitely got food poisoning. Never eating here again
